Abstract: This invention relates to a vehicle hood assembly that is operative to raise the rearward and frontward portions of a vehicle hood. The system includes an actuator selectively extendable to raise the rearward portion of a vehicle hood from a first position to a higher second position. A striker of novel design enables the frontward portion of the hood to rise as the rearward portion rises when the striker is engaged with a latch member. The latch member may be disengaged from the striker without extending the actuator, enabling the hood to reach a third position ideal for vehicle service and thus allowing a nonreversible-type actuator to be employed. A method of elevating the vehicle hood with respect to the vehicle body is also provided.

Abstract: A hood elevation system for a vehicle includes an actuator configured to selectively move at least a portion of a vehicle hood between an elevated and a retracted position. The hood elevation system also includes a self-locking mechanism configured to allow movement of the hood between the elevated and retracted positions initiated by the actuator, but to resist retraction of the hood as a result of certain loads applied to the hood. The self-locking mechanism thus enables repeated elevation and retraction of the hood. In a preferred embodiment, the self-locking mechanism is configured to deform, thereby absorbing energy from an impact to the hood.
